A Hydrogen atom can be thought of as a positive nucleus with a negatively charged electron, orbiting around it in a circular orbit of radius 5x10-11 m. This orbiting electron can be thought of as a current. Since the electron zips around 7x1015 times per second, and has a charge of 1.6x10-19 C, this amounts to a current of 1x10-3 Amps or 1 mA. What is the magnetic field at the center of the atom, produced by this current?

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.
